[vtkusers] using 3rd party shared libs with wrapping enabled

[Luke J West]

Hi, I've written some VTK classes which use a third party shared library, and 
are working fine. 
 
However, I am now tying to incorporate them into VTK so that my users can 
access them from TCL and python, but I've not been able to get VTK to see the 
libraries at build time - and at the point where it tries to build the TCL 
wrappers in particular. 
 
At the end is a transcript of what happens when I type make. 
 
FYI - during the ccmake step, I append the -L and -l options appropriate for 
the third party libraries to the following variables... 
 
 CMAKE_CXX_FLAGS 
 CMAKE_EXE_LINKER_FLAGS 
 CMAKE_MODULE_LINKER_FLAGS 
 CMAKE_SHARED_LINKER_FLAGS 
 
As far as I can see, that's everywhere, but have I missed something? 
Is there anywhere else I need to specify libraries? 
 
I've gotten as far as I can with this and would REALLY REALLY appreciate input 
from anyone who has successfully or unsuccessfully incoporated code (that uses 
an external shared library) into VTK. 
 
If I get this sussed - I'll write a howto for the community. 
Thanks very much, 
 
Luke
